方式一：
public partial class Form1 : Form
{
private delegate void FlushClient();//代理
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
Thread thread = new Thread(CrossThreadFlush);
thread.IsBackground = true;
thread.Start();
}
private void CrossThreadFlush()
{
while (true)
{
//將sleep和無限循環(huán)放在等待異步的外面
Thread.Sleep(1000);
ThreadFunction();
}
}
private void ThreadFunction()
{
if (this.textBox1.InvokeRequired)//等待異步
{
FlushClient fc = new FlushClient(ThreadFunction);
this.Invoke(fc);//通過代理調(diào)用刷新方法
}
else
{
this.textBox1.Text = DateTime.Now.ToString();
}
}
}
此方法2.0及以上
方法二：
private void ControlThread()
{
MethodInvoker TextBox1Show = new MethodInvoker(myControl);
BeginInvoke(TextBox1Show);
}
private void myControl()
{
textBox1.Text = "kdkkdkk2";
}
方法三：
this.Invoke((EventHandler)(delegate {}));
